365.add support of custom codecs in topics

[ekuvardin]

Finally after all discussion try to implement feature
#365

What major changes:

1. Replace Codec enum to number
2. Add ability to write custom codec using CodecRegistry local to TopicClient
3. Changed a lot of interface. Some interfaces can't be change in backward compability(they use enum)
   methods that can be used in backward compability mark as deprecated
   (it's all syn/async reader/writer)
4. Pass CodecRegistry to any ReaderImpl/Writer/Impl
5. Write 3 new test classes
   5.1 Test on custom codec + include test on all existed predefind codec
   5.2 Test on register
   5.3 Test on old deprecated methods

To use custom codec:

1. Implement interface CustomTopicCodec
2. Write your implementation.
3. Register Codec
4. For writer - specify codec in WritterSettings
5. For readers - for TopicClient it have to be registered
   Summary

        CustomTopicCodec codec1 = new CustomCustomTopicCode(1);
        client1.registerCodec(10113, codec1);
          WriterSettings settings = WriterSettings.newBuilder()
                .setTopicPath(topicName)
                .setCodec(10113)
                .build();

Seems next days try to pass all tests for all jdks

Tests YdbTopicsIntegrationTest.step03_readNextHalfWithoutCommit and YdbTopicsIntegrationTest.step04_readNextHalfWithCommit flaps, so you don't need to fix them. Just rerun

What have changed, please take a look at code

1. Codec now is an interface. All custom and predefined topics must override it's methods.
   Predefined codec now is a singleton.
2. Remove unregister codec. CodecRegistry under the hood contains HashMap cause works in a single thread
3. Remove old deprecated classes
4. Mark one test with ignore YdbTopicsCodecIntegrationTest.writeWithCustomCodec10000 - that's a pity. We already discussed about it, that SyncWriter have some bugs with flush.
5. CI hasn't passed cause
   java.util.List<java.lang.Integer> cannot be converted to java.util.List<tech.ydb.topic.description.Codec>
   in examples
   Seems we have to change examples in ydb-cookbook
